Hi all I'm new to this forum and have a big question to all your brains. Just before christmas, my block went down due to a crack (don't ask why) I got hold of a new block, had the head welded due to corrosion, got it shimmed, lapped valves, changed valve seals, installed new chain set, head gasket, bolts ect. everything by the book. I got the engine mocked in to my Sharan, big job though. got it started up, it ran fine, smoked a bit of white smoke from the exhaust, probably water in the cat, let it idle for some time, everything looked fine, then i pulled the oil filler cap and noticd mayo,
